Abstract:
The rise of demand for mobile and broadband communication has caused a
worldwide requirement of sophisticated transmitters. High volume and low-cost
manufacturing of semiconductor optoelectronic devices are playing an integral
role in allowing for the deployment of high-speed communication links. Requirements
of side mode suppression, reducing nonlinearities, reducing relative
intensity noises and chirps, enhancing the bandwidth are key parameters that
are leading for the enhancement of quality and the performance of fiber optic
communication system. Optical injection locking (OIL) is one technique to overcome
these limitations arising in developing better optical transmitters. Improved
device performances can be achieved by locking the high-quality phase and frequency
of the master laser to a low-quality slave laser. In this research, a proper
optical injection locking system will be developed and characterized by the perspective
of improving certain parameters in optical communication systems. A
simulation model will be developed and then the characterization will be done
for the locking range, bandwidth, amplitude, and phase noise transfer function.
The anticipated output will be helpful for several applications like developing optical
synchronization in phase-sensitive amplifiers which is useful for improving
the transparent length and the operating margins of the optical network system.
Also, it will build up a pathway to increase the speed of the optical communication
system by the increment of the bandwidth.
